Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522682, here are decompositions:

13 + 31522669 = 31522682
19 + 31522663 = 31522682
223 + 31522459 = 31522682
241 + 31522441 = 31522682
271 + 31522411 = 31522682
439 + 31522243 = 31522682
463 + 31522219 = 31522682
661 + 31522021 = 31522682

Showing the first eight; more decompositions exist.
